Washroom sealing in Pulborough

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Keep washrooms out of use until we say the sealant has cured
  • Tell us about infection-control or permit rules before we quote
  • Inspect washroom sealant regularly
  • Brief cleaning staff to treat joints gently

Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

How we handle washroom sealing in Pulborough

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on urinals and WCs, accessible toilets and changing rooms and showers, trays and wet room floors, and the usual reasons a site gets in touch are resealing that didn’t last because the old bead stayed and mould spotting along silicone joints. A single leaking joint is often how a building in Pulborough first comes to us: we look at the rest while we’re there and tell you what we find.

Around Pulborough, washroom work normally comes one building at a time. A list and photos let us quote and plan so it’s done in one visit where possible.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Commercial washrooms in Pulborough

Pulborough is about 41 miles from central London, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.

Schools such as St Mary's Church of England Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays. Colleges such as Brinsbury College, 2.4 miles to the north-east of Pulborough, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Pulborough is about 10 miles north of Littlehampton, in West Sussex. We cover Pulborough, with the same fixed quotes and 12-month guarantee as everywhere else. Across West Sussex, 373 places are covered, including Pulborough. There’s a separate page for Brighton, about 18 miles away.

What we are called out for in Pulborough

Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.

If one of these sounds familiar, it’s time for a closer look:

  • Shower tray joints that have opened up
  • Discoloured joints around urinals and WC pans
  • Washrooms that look worn because of the sealant
  • Failed sealant in a tea point or staff kitchen

On an industrial estate such as Station Approach Industrial Estate, 0.5 miles to the west of Pulborough, staff toilets, showers and canteens are where sanitary sealant takes the most wear.

What your quote should include

  • Will RAMS and insurance details be available?
  • Their pre-qualification and accreditations
  • Will failed sealant be removed rather than covered?
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For a site in Pulborough, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Each room is handed back once the sealant has had its cure time.

Before we start on site

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Point out any areas we must not close

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Your questions answered

Can you work around term dates at a campus such as Brinsbury College?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Will the toilets in our Pulborough building be out of use?

Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Will cleaning remove black mould from sealant?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.

How do I request a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

Do you need to remove the old sealant?

We strip every bit of the failed bead and wipe away the residue first. That’s what makes the new joint last.

What the job involves on each surface

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.

Healthcare and care settings

Assisted bathrooms and accessible toilets get heavy use so their sealant tends to fail sooner.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • A room that stays damp because ventilation isn’t working
  • Panel boards already damaged by water
  • Leaks through tanking or membranes below the finishes

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.
